Description:The Daily Digit today is 43.8 gallons. That's how much soda an average American drank in 2012, according to Beverage Digest, a publication that covers the industry. Now PepsiCo wants to keep that up, while, at the same time, maintain a consistent flow of money. That's why the company is tweaking its pricing policies to wean consumers off the habit of buying soda only when it is on sale. And it's doing so by narrowing the gap between soda prices on holidays and regular days.(1:14)
